ER-SW Series Programmable AC Power Source

ERSW series Programmable AC Power Sources have the ability to simulate the AC voltage and frequency used in all countries. They are excellent instruments for R&D, design production testing/evaluation,and QA verification. In addition, the frequency range covers 500 Hz, making these products ideal for commercial and defense avionics applications.

The ERSW series delivers maximum rated power for any adjustable output voltage up to 300Vac (L-N) / 520Vac (L-L )for 3 phase units, and at any adjustable frequency between 40Hz to 500 Hz.

It integrates IGBT made by Mitsubishi, Siemens, and Infineon, and combines microprocessor and ARM &DSP control design together for quick response and higher reliability and parallel operation.
